- The present disclosure relates to the technical field of a structure, a display apparatus and a method of molding the structure. Specifically, the present disclosure relates to the technical field of reducing the manufacturing cost and improving the design freedom by forming a molded product by using extrusion and then folding the molded product.
- A display including a display surface on which an image is displayed is provided in a display apparatus of various electronic devices, such as a television receiver or a personal computer. For example, a diffuser plate, an optical sheet and the like are disposed on the rear face of the display, and the panel module includes the display, the diffuser plate, the optical sheet and the like.
- A bezel is provided in such a display apparatus as a member which maintains the peripheral portion of the panel module. For example, the bezel is provided in a frame shape, includes a portion which extends in the horizontal direction and a portion which extends in the vertical direction, and is configured such that the portions are orthogonal to each other.
- Such a structure of a non-linear shape such as a bezel is generally formed using injection molding which uses a molding die including a core mold and a cavity mold (for example, refer to Japanese Unexamined Patent Application Publication No. 2010-237474).
- The formation of the structure such as a bezel using a molding die is performed by filling a cavity formed inside the molding die with a molten resin, and after cooling the molten resin, releasing the mold and pushing out the molded product using an ejector pin or the like.
- However, in the formation of a structure using injection molding as disclosed in Japanese Unexamined Patent Application Publication No. 2010-237474, since the manufacturing cost of the molding die is high, the manufacturing cost of the structure to be formed also becomes high.
- In addition, when the shape of the structure is modified, it is necessary to manufacture a molding die so as to include a cavity of a shape appropriate for the structure every time there is a modification, and there is also a problem in that the design freedom is poor.
- Therefore, it is desirable to provide a structure, a display apparatus and a method of molding the structure according to an embodiment of the present disclosure which solve the above problems, decrease the manufacturing costs and increase the design freedom.
- First, according to an embodiment of the present disclosure, there is provided a structure in which a folding notch, which is open in a direction orthogonal to an extrusion direction, is formed on a molded product formed using profile extrusion, each portion of an open edge of the folding notch is formed as a first matching portion and a second matching portion which are separate or continuous in the extrusion direction, and the molded product is folded such that the first matching portion and the second matching portion face each other.

- Since both the first matching portion and the second matching portion are formed in a straight line shape, it is easy to form the folding notch, the processing precision of the folding notch is high, and, when the first matching portion and the second matching portion face each other, a gap is not easily formed therebetween.
- Sixth, in the structure described above, it is desirable that the first matching portion and the second matching portion be formed in a V-shape.
- The first matching portion and the second matching portion are formed in a V-shape. Therefore, the formation of the folding notch is even easier, and the processing precision of the folding notch is also high.
- Seventh, in the structure described above, it is desirable that a first face portion and a second face portion which each extend in the extrusion direction orthogonal to each other be provided, and that the folding notch be formed in the first face portion.
- The first face portion and the second face portion which each extend in the extrusion direction orthogonal to each other are provided, and the folding notch is formed in the first face portion.

- The best mode shown below applies the display apparatus of the embodiment of the present disclosure to a television receiver including a flat display panel, the structure of the embodiment of the present disclosure to a bezel of the television receiver, and the method of molding the structure of the embodiment of the present disclosure to the method of molding the bezel.
- Furthermore, the application scope of the display apparatus, the structure, and the method of molding the structure of the embodiment of the present disclosure is not limited to a television receiver including a flat display panel, a bezel of the television receiver, and the method of molding the bezel, respectively.
- The application scope of the display apparatus of the embodiment of the present disclosure can be widely applied to various display apparatuses, such as a monitor used in other various television receivers, personal computers and the like, regardless of the type of the display.
- In addition, the application scope of the structure and the method of molding the structure of the embodiment of the present disclosure can be widely applied to various structures formed using an extrusion apparatus and to the methods of molding the structures.
- For example, the display apparatus (the television receiver) 1 is formed in a substantially rectangular shape, which is horizontally long and planar, and the various necessary portions are disposed in the housing 2 (refer to
FIG. 1 ). For example, thedisplay apparatus 1 is maintained by a stand (not shown). - The
housing 2 includes abezel 3 positioned on the front side, aback chassis 4 positioned on the rear side, and a rear cover 5 attached to the rear face side of the back chassis 4 (refer toFIGS. 1 and 2 ). - For example, the
bezel 3 is formed in a substantially rectangular frame shape, and includeshorizontal portions 6 and 7 positioned at the top and the bottom, andvertical portions horizontal portions 6 and 7 are provided to extend in the horizontal direction, and thevertical portions - The
bezel 3 is provided as a structure which is formed by folding the molded product, described below and formed using profile extrusion, into a predetermined shape. For example, thebezel 3 is formed from a resin material, a metal material, a ceramic material or the like. Thebezel 3 includes a front face portion (a first face portion) 9, a circumferential face portion (a second face portion) 10 and a rear face portion (a third face portion) 11 (refer toFIG. 3 ). - A
groove portion 9 a which extends in the circumferential direction is formed in the peripheral portion of the front face of the front face portion 9 (refer toFIGS. 1 and 3 ).Welding ribs front face portion 9 so as to be separated from each other in the interior-exterior direction (vertically or horizontally). On the rear face of thefront face portion 9, an engagingprotrusion portion 9 c which protrudes to the rear is provided on the outside of thewelding ribs - Furthermore, due to the
groove portion 9 a being formed in a position near the periphery of thefront face portion 9 of thebezel 3, the width of thefront face portion 9 appears to be smaller than the actual width when thebezel 3 is viewed from the outside. Therefore, thebezel 3 appears to be small and the design of thedisplay apparatus 1 is improved. - A
cushion 12 which extends in the circumferential direction is provided in the inner peripheral portion of the rear face of thefront face portion 9. Furthermore, it is possible to form thecushion 12 by extruding a soft, different material such as rubber at the same time as the resin material or the like which is thebezel 3 material. - The
circumferential face portion 10 is provided so as to protrude from the peripheral portion of thefront face portion 9 to the rear. An engagingprotrusion portion 10 a which protrudes inward is provided in a position near the rear end of thecircumferential face portion 10. - The
rear face portion 11 is provided so as to protrude inward from the rear end portion of thecircumferential face portion 10. The engagingbeam 11 a which protrudes forward is provided in the inner peripheral portion of therear face portion 11. - A maintaining
space 13 is formed by the peripheral portion of thefront face portion 9, thecircumferential face portion 10 and therear face portion 11. The maintainingspace 13 maintains a member (not shown) or the like which is disposed on the peripheral portion of thepanel module 14 or on the peripheral side of the panel module 14 (refer toFIG. 1 ). - A display on which an image is displayed and a diffuser plate which diffuses light incident to the display, a plurality of optical sheets which each exhibit a predetermined function in relation to the light incident to the display, a light source which functions as a back light, a light guide plate which guides the light in a predetermined direction, a maintaining bracket and the like are disposed to form the
panel module 14. - In a state in which the
panel module 14 is maintained in thebezel 3, the front face of thepanel module 14 is pressed against thecushion 12, thereby thepanel module 14 is protected by thecushion 12. - The method of molding the
bezel 3 provided as the structure is described below (refer toFIGS. 4 to 10 ). - First, the molded
product 50 is formed using extrusion prior to being formed as the structure (refer toFIG. 4 ). Since the moldedproduct 50 is formed using an extrusion apparatus, the cross-sectional shape is the same in all positions, and the moldedproduct 50 is formed in a shape that extends in one direction. - The cross-sectional shape of the molded
product 50 is the same as the cross-sectional shape shown inFIG. 3 . The moldedproduct 50 is formed from afirst portion 51, a second portion 52 and a third portion 53, which are respectively formed as thefront face portion 9, thecircumferential face portion 10 and therear face portion 11. Accordingly, agroove portion 51 a is formed in thefirst portion 51 as thegroove portion 9 a. - Next,
folding notches first portion 51 of the moldedproduct 50 using machining, for example. In addition, notches (not shown) are also formed in the third portion 53 at the same positions as the positions at which thefolding notches - For example, in the molded
product 50, four of thefolding notches product 50 is divided into five portions by thefolding notches first portion 51 and each of the notches formed in the third portion 53, for example. - The five portions are as follows: a
base portion 55 formed as the horizontal portion 6;central portions base portion 55, and are respectively formed as thevertical portions portions vertical portions horizontal portion 7. In addition, thebase portion 55 is longer than thecentral portion 56, and the total length of theend portions base portion 55. - The further from the second portion 52, the wider the width of the
folding notch 54 becomes, and thefolding notch 54 is formed in a substantially isosceles triangle shape with a vertical angle of 45° (refer toFIGS. 5 and 6 ). Accordingly, the open edge of thefolding notch 54 is configured to include two portions which are inclined in relation to thefirst portion 51 in the longitudinal direction (the extrusion direction of the extrusion apparatus of the molded product 50), one of which is formed as thefirst matching portion 54 a, and the other is formed as thesecond matching portion 54 b. The further from the second portion 52, the more thefirst matching portion 54 a and thesecond matching portion 54 b separate from each other. Thefirst matching portion 54 a and thesecond matching portion 54 b are substantially V-shaped. -
Small openings first portion 51 in communication with thefolding notches small opening 58 may also be formed at the same time as the formation of thefolding notch 54, and may also be formed after the formation of thefolding notch 54. In addition, it is also possible to form thesmall opening 58 first, and form thefolding notch 54 after the formation of thesmall opening 58. - For example, the
small opening 58 is formed in a substantially rectangular shape, is penetrated in the thickness direction of thefirst portion 51, and both ends in the circumferential direction are continuous with each end of the second portion 52 side of thefirst matching portion 54 a and thesecond matching portion 54 b, respectively. Thesmall opening 58 is formed in thegroove portion 51 a. - Furthermore, a small opening similar to the
small opening 58 may also be formed in the third portion 53 to be continuous with the notch. - Next, each portion is folded by 90° in the portions in which the
folding notches FIGS. 7 and 8 ). In other words, thecentral portions base portion 55, and theend portions central portions - Due to each portion being folded in this manner, the
first matching portions second matching portions folding notches FIG. 7 ). - As described above, the
central portions base portion 55, and theend portions central portions bezel 3 of a frame shape is formed (refer toFIG. 8 ). At this time, theend portions - In a state in which the
bezel 3 is formed by each portion being folded as described above, it is desirable that fixingmembers central portions base portion 55, and, between theend portions central portions FIGS. 9 and 10 ). - For example, the fixing
member 15 is a plate-shaped metal member formed in an L-shape, and is joined to the rear face of thefront face portion 9. Examples of methods of joining the fixingmember 15 include welding, screw fastening and adhesion. - Furthermore, it is possible to use a laminated steel plate, in which a resin material is laminated onto one face of a plate-shaped metal material, as the fixing
member 15. When such a laminated steel plate is used, in a case in which thebezel 3 is formed from a resin material, it is possible to join the resin material of the laminated steel plate to thebezel 3 using ultrasonic welding. In this case, thewelding ribs member 15 against thewelding ribs member 15 to thebezel 3 in a short time of less than one second. - As described above, in a state in which each portion is folded and the
first matching portion 54 a and thesecond matching portion 54 b face each other, there is a concern that a so-called bulge will occur in the surface of the structure. The bulge in the surface of the structure is the bulging of the portions which are folded, in particular, the end portion of the second portion 52 side, at which thefirst matching portion 54 a and thesecond matching portion 54 b approach each other. - However, since the
small opening 58 which communicates with thefolding notch 54 is formed in thefirst portion 51, the surface of the structure which is to protrude to the outside due to folding is positioned in thesmall opening 58, and it is possible to reduce the bulging of the surface of the structure. - In addition, when each of the portions is folded, the end portions of the second portion 52 side of the
first matching portion 54 a and thesecond matching portion 54 b are deformed. There is a concern that the degree of deformation in these portions is inconsistent according to the processing precision of thefolding notch 54. However, since thesmall opening 58 is formed in the portion at which deformation occurs, the irregularities during the deformation are absorbed by thesmall opening 58, and it is possible to secure an appropriate folding state of each of the portions. - Furthermore, the
groove portion 51 a (9 a) which extends in the longitudinal direction (the extrusion direction) is formed in the moldedproduct 50. Since thesmall opening 58 is formed in thegroove portion 51 a, even when the surface of the structure bulges, the bulge is present in thegroove portion 51 a, the state of the bulge of the surface of the structure is not obvious from the outside, and it is possible to improve the visual properties of thebezel 3 and thedisplay apparatus 1. - Yet furthermore, since the
small opening 58 is present in thegroove portion 51 a, thesmall opening 58 is not obvious in a state in which each of the portions is folded and thefirst matching portion 54 a and thesecond matching portion 54 b face each other. Therefore, it is possible to further improve the visual properties of thebezel 3 and thedisplay apparatus 1. - Furthermore, the
first matching portion 54 a and thesecond matching portion 54 b of thefolding notch 54 formed in the moldedproduct 50 are both formed in a straight-line shape. Accordingly, it is easy to form thefolding notch 54, the processing precision of thefolding notch 54 is high, and when thefirst matching portion 54 a and thesecond matching portion 54 b face each other, a gap is not easily formed therebetween. Therefore, it is possible to form thebezel 3 with a high molding precision. - In addition, the
first matching portion 54 a and thesecond matching portion 54 b are substantially formed in a V-shape. Therefore, the formation of thefolding notch 54 is even easier, the processing precision of thefolding notch 54 is also higher, and it is possible to form thebezel 3 with an even higher molding precision. - Furthermore, as described above, a plurality of the
folding notches product 50. Therefore, it is possible to form the same number of folding locations as the number of thefolding notches - In addition, the
bezel 3 is formed such that the first portion 51 (the front face portion 9) and the second portion 52 (the circumferential face portion 10) are orthogonal to each other. The second portion 52 (the circumferential face portion 10) and the third portion 53 (the rear face portion 11) are formed orthogonal to each other, and thefolding notches first portion 51. - Accordingly, the
bezel 3 includes orthogonal portions, thefolding notches first face portion 51, and the notches or the like are not formed on the second portion 52 and the third portion 53. Therefore, it is possible to secure high rigidity in the entirety of thebezel 3. - An example was described above in which four of the
folding notches product 50, and the moldedproduct 50 is divided into the five portions of thebase portion 55, thecentral portions end portions product 50 is divided is not limited to five, and the number by which the moldedproduct 50 is divided is arbitrary. - For example, two of the
folding notches product 50, and the moldedproduct 50 may also be divided into the three portions of thebase portion 55 and thecentral portions 56 and 56 (refer toFIGS. 11 and 12 ). In this case, the horizontal portion 6 and thevertical portions base portion 55 and thecentral portions horizontal portion 7, it is possible to form thebezel 3 by joining both end portions of the members 16 and 16 to thecentral portions - In addition, the
small opening 58 formed in a rectangular shape was shown above as an example, however, asmall opening 58A may also be formed with a curved periphery (refer toFIGS. 13 and 14 ). For example, thesmall opening 58A is formed in a substantially semicircular shape. - Since there are no corner portions in the periphery of the
small opening 58A due to thesmall opening 58A being formed with a curved periphery in this manner, stress is not apt to concentrate in the periphery of thesmall opening 58A during the folding of each portion, and it is possible to prevent the occurrence of cracks in thebezel 3. - Furthermore, the
folding notch 54 including thefirst matching portion 54 a and thesecond matching portion 54 b, each of which having a straight-line shape, was exemplified above, however, it is possible to form thefolding notch 54 in such shapes as are described below. - For example, a
folding notch 54A including afirst matching portion 54 c and asecond matching portion 54 d, which are respectively configured by a plurality of straight lines, may also be formed (refer toFIG. 15 ). In addition, afolding notch 54B including afirst matching portion 54 e and asecond matching portion 54 f of a curved line shape may also be formed (refer toFIG. 16 ). - In addition, the first matching portion and the second matching portion may also be configured by an arbitrary combination of straight lines and curved lines, and the number of straight lines and curved lines is also arbitrary.
- Next, a example is described in which the
bezel 3 is formed in which the widths of thehorizontal portions 6 and 7 and thevertical portions FIGS. 17 to 21 ). - In the example in which the widths differ, for example, the
horizontal portions 6 and 7 are formed by being folded, and thevertical portions horizontal portions 6 and 7 may also be formed without being folded, and thevertical portions horizontal portions 6 and 7 are formed by being folded is shown. - First, the molded
products products FIGS. 17 and 18 ). - The
horizontal portions 6 and 7 are respectively formed from the moldedproducts vertical portions products product 50A and the moldedproduct 50B are configured by thefirst portion 51, the second portion 52 and the third portion 53 in the same manner as the moldedproduct 50 and have the same general structure, only the configuration which differs from the moldedproduct 50 will be described in detail below. - The width of the molded
product 50B is smaller than the width in the longitudinal direction of the moldedproduct 50A excluding both end portions. - The
folding notches product 50A in the longitudinal direction, respectively. The end portion closer to the outside than thefolding notch 54 in the longitudinal direction of the moldedproduct 50A is provided as anarrow width portion 60 which has a smaller width than the other portions. In addition, acontact edge 61, which is continuous with thesecond matching portion 54 b and extends in the horizontal direction, is formed in thenarrow width portion 60. - A
contact edge 62 which extends in the vertical direction is formed on a portion which is continuous with the inside of thefolding notch 54 in the longitudinal direction of the moldedproduct 50A. Thecontact edge 62 is the same length as thecontact edge 61. - An
inclined edge 63 is formed on the moldedproduct 50A to be continuous with thecontact edge 62. - An
inclined edge 64 is formed on both end portions in the longitudinal direction of the moldedproduct 50B. Theinclined edge 64 is formed at the same length as theinclined edge 63 of the moldedproduct 50A. - In the molded
product 50A, thenarrow width portion 60 is folded by 90° in the portion at which thefolding notch 54 is formed (refer toFIG. 18 ). - By folding the
narrow width portion 60, thefirst matching portion 54 a and thesecond matching portion 54 b of thefolding notch 54 face each other, and thecontact edge 61 and thecontact edge 62 face each other. - Next, the molded
product 50A and the moldedproduct 50B are joined and thebezel 3 is formed. When the moldedproduct 50A and the moldedproduct 50B are joined, theinclined edge 63 and theinclined edge 64 face each other, and thetip edge 65 of thenarrow width portion 60 and thetip edge 66 of the moldedproduct 50B face each other. - In a state in which the molded
product 50A and the moldedproduct 50B are joined, it is desirable, for example, that both be fixed using a fixing unit such as the fixingmember 15. - Furthermore, it is also possible to use a fixing
member 17 such as that described below instead of the fixingmember 15. Furthermore, an example is shown below in which thehorizontal portion 7 and thevertical portion 8 are fixed by the fixingmember 17. - The fixing
member 17 is formed from a firstjoint portion 18 which extends horizontally and a secondjoint portion 19 which is continuous with one end portion of the firstjoint portion 18 and extends vertically. The fixingmember 17 is formed such that the entirety thereof is L-shaped. - Engaging
portions joint portion 18 so as to be elastically deformable. The engagingportions joint portion 18. - Engaging
concave portions joint portion 19. The engagingconcave portions joint portion 19. - In the fixing
member 17 configured as described above, first, the engagingportions protrusion portion 9 c of the horizontal portion 6 and theengaging beam 11 a, respectively (refer toFIG. 20 ). The engagingportions protrusion portion 9 c and theengaging beam 11 a as follows. The firstjoint portion 18 is inserted into the maintainingspace 13 of the horizontal portion 6 from above, and during the insertion, the engagingportions protrusion portion 9 c and theengaging beam 11 a. Subsequently, the engagingportions - In this manner, the engaging
portions protrusion portion 9 c and theengaging beam 11 a due to the firstjoint portion 18 being inserted into the maintainingspace 13 of the horizontal portion 6. Therefore, the operation is simple and it is possible to improve the operability. - Next, the
vertical portion 8 is moved downward, thevertical portion 8 is caused to slide in relation to the secondjoint portion 19, and the engagingconcave portions protrusion portion 9 c, the engagingbeam 11 a and the engagingprotrusion portion 10 a, respectively. - In this manner, the engaging
concave portions protrusion portion 9 c, the engagingbeam 11 a and the engagingprotrusion portion 10 a due to thevertical portion 8 being caused to slide in relation to the secondjoint portion 19. Therefore, the operation is simple and it is possible to improve the operability. - Furthermore, in contrast with the above description, the second
joint portion 19 may also be joined to thevertical portion 8 by moving thehorizontal portion 7 to which the fixingmember 17 is joined upward and sliding the secondjoint portion 19 in relation to thevertical portion 8. - As described above, the engaging
portions protrusion portion 9 c and theengaging beam 11 a, respectively, and the engagingconcave portions protrusion portion 9 c, the engagingbeam 11 a and the engagingprotrusion portion 10 a, respectively. Therefore, thehorizontal portion 7 and thevertical portion 8 are joined and fixed by the fixingmember 17. - In a state in which the
horizontal portions 6 and 7 and thevertical portions members members horizontal portions 6 and 7 and thevertical portions bezel 3. - As described above, the
folding notches 54 open in a direction orthogonal to the extrusion direction (the longitudinal direction) are formed on the moldedproducts products first matching portion 54 a and thesecond matching portion 54 b face each other, and thebezel 3 is formed. - Accordingly, since the molded
products bezel 3 are formed using extrusion and not injection molding, it is possible to reduce the manufacturing cost of thebezel 3. - In addition, even when the shape of the
bezel 3 is modified, it is not necessary to manufacture a new molding die appropriate for thebezel 3, as is in the injection molding, and it is possible to improve the design freedom accordingly. - Furthermore, in the formation of the structure using a molding die, in order to facilitate the pushing out of the structure using an ejector pin, it is necessary to form a draft angle in the molding die. Accordingly, the structure is thick and becomes large.
- However, in the
display apparatus 1, since thebezel 3 is formed using extrusion, it is not necessary to form a draft angle. Accordingly, it is possible to miniaturize thebezel 3 and thedisplay apparatus 1. - Yet furthermore, it is not necessary to form the undercut portion using a slider as in the injection molding, and it is possible to form the undercut portion without bringing about a rise in the manufacturing cost.
- In addition, by forming the
bezel 3 using extrusion, it is also possible to perform multicolor molding or decoration by applying a film. Therefore, it is possible to improve the design freedom and the design of thebezel 3. - The present disclosure may also adopt configurations such as the following.
